The photovoltaic power generation in winter is affected by many factors such as solar altitude angle, sunshine time, strong wind, low temperature, snow cover, haze, etc., which will affect the power generation efficiency and system stability of the photovoltaic power station. However, how much will power generation be affected?
As you can see from the chart above, in 2019-2022,The photovoltaic power generation in the fourth quarter is significantly lower than that in the third quarterIn 2022Photovoltaic power generation in the fourth quarter is higher than in the third quarter16% reduction；In 2021, due to the impact of the new PV installed capacity in the fourth quarter being significantly higher than that in the third quarter, the power generation in the fourth quarter increased, with a decrease of only 6%.In the fourth quarter of 2020, power generation decreased by 6% compared with the third quarter (mainly considering the impact of the epidemic, and the power generation in the third quarter itself was not high).In 2019, the reduction even reached, mainly because the speed of PV grid connection before 2019 was not fast, excluding the impact of the factors of new capacity being connected to the grid.
Overall, there is no doubt that the amount of photovoltaic power generation in winter will be significantly reduced, and the reduction rate will be at least 16%, regardless of the impact of the increase in new photovoltaic installed capacity
In terms of regions, photovoltaic power generation is a strong provinceShanxi Province, Xinjiang Uygur Autonomous Region, Anhui Province, Shandong Province, Guizhou Province and other provinces saw the largest decline in photovoltaic power generation in winter, the decline is inAbove. So, the question arises again, do you know why these areas have seen the biggest decline in PV generation?
